A globally unique identifier (guid,globally unique Identifier) is also known as a UUID (universally unique Identifier). A GUID is a 128-bit numeric identifier generated by the algorithm in binary length. The GUID is formatted as "Xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx", where X is a 32-bit hexadecimal number in the range 0-9 or a-f. Ideally, no computer or cluster of computers will generate two identical GUIDs. The total number of GUIDs reached 2^128 (3.4x10^38), so the probability of randomly g

someone encounters a bug or is inconvenient to use, you are welcome to raise it so that you can continue to improve it. I hope you will forgive me for any shortcomings in the plug-ins written after learning.
